Reduced electric-octupole transition probabilities, B(E3; 0+1 → 3-1) -: An update

A previous compilation of excitation energies E-x(3(1)(-)) and reduced electric-octupole transition probabilities B(E3; 0(1)(+) --> 3(1)(-)) for first 3(-) states of even-even nuclides, which covered the literature to March 1988, has been updated to cover the literature to the end of 2000. Data obtained from various experimental procedures are tabulated. The final table presents adopted values of B(E3;0(1)(+) --> 3(1)(-)), together with the E3 transition strengths \M(E3)\(2) in Weisskopf units. Plots of \M(E3)\(2) versus mass number A, atomic number Z, and neutron number N confirm the existence of structure suggested in the earlier work. (C) 2001 Elsevier Science (USA).
